If you take the time to ask a cop why they need to see your license they might say something like, 'Because I don't know who you are' - as if identity is a product of the state and having that piece of plastic somehow gives the cop any extra insight. But try putting that the other way - insist that you need to see their license for the same reason. 'Well, officer, how do I know who you are? We've never met so, to me, you're just a stranger making threats.'
Most people don't know this, but if a cop stops you in North America... you are de facto "under arrest". The cop can use any force necessary to go about his business since you are "under arrest". HIs/her first job is to determine if you are a threat, so being uncooperative will rapidly escalate the situation. I almost got shot a few years ago in a similar, completely benign situation. Kinda like this dude.
If you ever get a cop on the witness stand, be sure to ask what they would have done had you not complied. That tends to wipe out any notion of consent.
What % of the population would defend the cop in this situation? Way too many. To recognize the tyranny this represents is to accept responsibility for it, partially, if you support the idea of govt. That is an inconvenient truth that is "felt" not openly acknowledged. To openly face the tyranny would be too painful and frightening for most. Next they would have to think of all their responsibility. That is avoided by "willful ignorance", i.e., compartmentalizing. It represents a disrespect for the truth that will corrupt their entire life experience, and leave them wondering sometimes "why me?"
